Eaton FER1D2821SZ Bayonet Connector - Fire & Smoke Cert
Part Number: FER1D2821SZ
Quick Summary
Eaton FER1D2821SZ is a fire and smoke certified bayonet connector designed for rugged electrical interconnects. Engineers face the challenge of meeting stringent safety standards without sacrificing reliability in vibration-heavy, temperature-extreme environments. This product carries fire and smoke certification, IP67 sealing, and RoHS/UL94 V0 compliance, providing assurance for regulated applications such as machinery, rail, and aerospace subsystems. By combining robust sealing with a compact aluminium shell, it minimizes ingress risk while simplifying quick-disconnect maintenance. The result is reduced downtime, lower maintenance cycles, and improved safety compliance across industrial automation and control networks, supported by compatible Souriau VGE1-FER1 series accessories and standard crimp contacts for 37 circuits.

FAQs
Install by aligning the straight plug with the mating receptacle, then engage the thread coupling to secure the connection. Ensure the orientation is set to Y as specified, and use the appropriate 37 #16 crimp contacts. Verify IP67 sealing after assembly and tighten until the coupling seats fully to prevent ingress during operation.
Yes. FER1D2821SZ is part of the Souriau VGE1-FER1 family and uses 37 crimp contacts in a female socket configuration. Note that some connector accessories are not delivered and must be ordered separately to complete the assembly and seal integrity for your application.
Ideal for rugged automation panels, rail signaling, and machinery where fire and smoke certification and IP67 protection are essential. Its aluminium shell and high mating-cycle rating support durable use in harsh environments, including outdoor installations and coastal or industrial facilities, while maintaining reliable signal and power performance.
FER1D2821SZ carries fire and smoke certification, IP67 ingress protection, RoHS compliance, and UL94 V0 flammability rating with REACH adherence. These certifications ensure safety, environmental compliance, and regulatory acceptance in regulated industries, reducing risk during audits and accelerating project approvals for controlled equipment.
The connector supports up to 500 mating cycles, suitable for recurring interconnections in automation and control networks. For maintenance, inspect the aluminium shell for signs of corrosion, verify the IP67 seal after installation, and replace worn contacts or gaskets as part of preventative maintenance to sustain performance in harsh environments.
